模型不确定下的做市行为

Market Making with Model Uncertainty

Hee Su Roh, Yinyu Ye

摘要:

保证金互助市场是一个交易平台,通过它,共同做市商可以同时清算多个或有债权市场。这个市场有几个独特的属性,在2000年代开始吸引金融业的注意力。例如,该平台将个人或有债权市场的流动性聚集到共同池中,同时保护做市商免受潜在的财务损失。本文的贡献是双重的。首先,我们提供了一个新的经济学解释的市场出清策略的同注分彩市场是众所周知的文献。同注分彩拍卖商等价于对未来或有事件具有极端模糊厌恶的做市商。其次,基于这种理论的理解,我们提出了一个新的市场出清算法,称为Boghtian Pari-mutuel机制(KPM)。KPM保留了同注分彩市场的许多有趣的特性,同时明确控制了做市商的模糊性厌恶。此外,KPM在计算上是高效的,因为它可以在多项式时间内求解。

英文摘要:

Pari-mutuel markets are trading platforms through which the common market maker simultaneously clears multiple contingent claims markets. This market has several distinctive properties that began attracting the attention of the financial industry in the 2000s. For example, the platform aggregates liquidity from the individual contingent claims market into the common pool while shielding the market maker from potential financial loss. The contribution of this paper is two-fold. First, we provide a new economic interpretation of the market-clearing strategy of a pari-mutuel market that is well known in the literature. The pari-mutuel auctioneer is shown to be equivalent to the market maker with extreme ambiguity aversion for the future contingent event. Second, based on this theoretical understanding, we present a new market-clearing algorithm called the Knightian Pari-mutuel Mechanism (KPM). The KPM retains many interesting properties of pari-mutuel markets while explicitly controlling for the market maker's ambiguity aversion. In addition, the KPM is computationally efficient in that it is solvable in polynomial time.
